SNOWJELOW.

.application led August 7, 1924. Se'rial No. 730,692.

To aZZ whom, t may concern:

Be it known t-hat lf, FRANK lV. BROWN, a citizen of the United States, residing at Fort Dodge, in the county of l/Vebster, State of liowa, have invented certain new and useful improvements in Snowplows, of which the following is a'specification.

This invention relates to plows especially adapted for removing snow.

Briefly stated, an important object of this invention is to provide a snow plow having novel means to scoop up the snow as it is encountered and direct it a substantial distance toone side of the road. A

A further object of theinvention is to provide a plow of the character speciiedhaving novel means whereby the discharge means of the plow maybe conveniently regulated so that the point to which the snow of spaced parallel transversely extending is thrown may be varied.

A further object of the invention is to provide a snow plow having a power unit for operating the snow pick-up and discharge means which is entirely separate and independent from the power unit of the propelling means such as a tractor.

A still further object of the invention is to provide a snow plow which is of highly simplified construction, durable in use, and cheap to manufacture.

@ther objects and advantages will be apparent during the course of the following descri tion.

In t e accompanying drawings forming a part of this application, and in which like numerals are employed to ldesignate like parts throughout the same,

are extended inwardly as indicatedy at 7 and,

are connected to a pair of substantially pary allel attaching means 8. Figure 7 illustrates that the attaching beams 8 may be arranged on opposite sides of a tractor or other propelling member 10 and connected thereto so that when the tractor is advanced, the plow will cut through the snow and operate on it in a manner to be described.

The frame 5 is also provided with a pair beams 9 on which a motor lOis mounted.

rlhe motor is preferably of the internal combustion engine type and has connection with a transmission 12 from which a shaft 14 extends. Theshaft 14 hasl connection with a chain or other suitable power transmitting member 16 which is in turn connected to a counter-shaft 16.

' The countershaft 16 is arranged in a housing 17, the ends of which are enlarged for the reception of beveled gears 18. Fig. 3 plainl illustrates that the beveled gears with pinions 19 of suitable shafts 20. The stub shafts 20 are carried by antifriction elements 2 1 in the enlarged end portions 22 of the housing 17 and the forward ends of the shafts 19 have connection in any suitable manner with combined snow wheel is provided with a plurality of radially arranged transversely curved blades 27 which directly contact with the snow. If desired, the forward edges of the blades 27 may be sharpened so as to eii'ectively cut through the snow. Also the rear edges of the blades 27 are provided with attaching flanges 28 adapted to be secured tothe members 25 by bolts, rivets, or other suitable fastening means.

Figures 3 and 4 plainly illustrate that the wheel or blades 25 are arranged side by side within separate and independent housings 30. Each housing'SO is provided with a fixed rim or wall 31, the ends of which are arranged in spaced relation as illustrated'in Figure 5. The spout 34 extends tangentially from the housing 30 and is provided with a pair of attaching extensions 35 and 36, the attaching extension 35 being secured to one end portion of the rim 31 by inwardly projecting flanges 37, while the attaching extension 36 is secured to the other .end of the rim 31 by means of inwardly extending guide flanges 39. It will be seen that the spout 34 may be adjusted circumferentially on the housing 30 and it may bel secured in a desired position by means of a fastening device 40 which extends through a longitudinal slot 42 in the attachingr extension 36.

27 and is thrown centrifugally through the the discharge spout 34 is securely and positively held in a set position. It is believed to be obvious that the point at which the snow is thrown may be regulated by an ad-` justment of the spout 34.

Figures 2 and 3 illustrate that a scoop 50 is located in advance of the wheels 25 and is supported by suitably stout side walls 52. As the snow approaches the wheels 25 it encounters a divide 54 which directs the snow into contact with the blades of the several wheels. The end portions of the scoop 50 are also curved upwardly, as indicated at 55, so as to direct the snow into the housings which receive the several cutter wheels. It is thus seen that gradually restricted entrance openings are provided at the inlet `ends of the housings and the snow is, therefore, prevented from packing about the openings. e l

In carrying out the invention the scoop is supported at/the proper level by shoes and by wheels 62 arranged rearwardly of the shoes. The shoes 60 may be provided with standards 63connected in any suitable manner to the spaced parallel side beams 6' of the main frame.

As illustrated in Figures 1 and 8, the weight of the scoop may be taken olf the shoes 60 and borne by the wheels 62. .The wheels 62 are carried by standards 104 slidable through, sleeves 105 carried bythe frame \5. The upper portions of the Standards 104 of which there are t'wo, have connection with levers 108 through the medium of connecting heads 109 and by reference to Figure 8, it will be seen that the `inner portions of the levers 108 are overlapped and have connection with a lifting chain 110. A lifting chain 112 or other suitable mechanism may be connected to the chain 110 and is suspended from a centrally located standard 114. n

lFigure 8 clearly illustrates that when the inner portions of the levers 108 are moved upwardly by the lifting mechanism the standards 104 will be moved downwardly whereby the weight of the scoop is borne by spouts 34 to opposite sides of the roadway. The snow maybe thrown a distance of one hundred feet or more thus clearing it off the roadway. Furthermore, as the snow isf' thrown with considerable force from the machine it will not fall in a row but will be spread over a ratheriwide area. Therefore, the snow will more rapidly melt.

A machine constructed in accordance with the present invention will effectively perform the desired work as it will cut a swath of snow three feet deep and extending for about a mile in one hour and thirty minutes.

It is to be understood that the form of the invention herein shown and described is to be taken merely as a preferred erample o f the same, and that such minor changes in arrangement and construction of parts may be'made as will remain within the spirit of the invention and the scope of the claims.

Having thus described lthe invention what I claim is: C,

'1. A snow plow comprising a pluralit of housings having rims the ends of whic .are in spaced relationship, spouts having ing a pairrof spaced kparallel transversely extending beams, a motor supported by said beams and having a transmission, a shaft extending from said transmission, atransversely extending counter shaft arranged at one side of said motor and having connection with the shaft of vsaid transmission, gears mounted nvsaid shaft, stub shafts arranged at the ends of the counter shaft, pinions mounted on said stub shafts and engaged with said gears, wheels connected to said stub shafts and having radial transversely curved blades, a, scoop for picking up the snow and applying the same to the transversely curved blades of said wheels. and-.a housing receiving said counter and stub shafts and said gears and being carried by said frame, said frame being provided with rearwardly extending .attaching beams adapted to be arranged on opposite sides of a separate tractor for propelling the plow.

3. In a snow plow, the combination of a frame, a scoop carried thereby, sleeves car,- ried by the frame, standards `movable through the sleeves and having ground en;y

4.V In a snow plow, the combination of a frame, a scoop carried thereby, sleeves carred `by the frame, standards movable through the sleeves and having ground engaging wheels, levers connected at the outer ends thereof` to thestandards, a chain connected to the inner ends of the 'levers whereby the standards may be moved downwardly to support the weight of the scoop, and shoes carried by the frame and normally bearing the Weight of the scoop. f
